You can find the area of Bonnue's backyard by comparing the hypotenuse of the garden to the hypotenuse of the back yard. If the hypotenuse of the garden is 10 (with the side lengths being 6, 8 and 10 - the longest is always the hypotenuse) and the hypotenuse of the back yard is 30, this is a scale factor of 3 (3 times longer).
This means the other two sides would also be 3 times longer.
6 yards x 3 = 18
8 yards x 3 = 24
To find the area using these dimensions, you will use the formula for finding the area of a triangle.
A = 1/2bh
A = 1/2 x 18 x 24
A = 216 square yards
The area of the backyard is 216 square yards.
The mistake is that they subtracted 21 instead of adding it. you would have had to added 21 to the left side to cancel it out and added 21 to the right side to get p= 55
Answer: Use calculations for population standard deviation.
Step-by-step explanation:
The population standard deviation is defined as
- a parameter which is a fixed value
- evaluated by considering individual in the population.
A sample standard deviation is defined as
- a statistic ( whose value is not fixed ).
- Evaluated from a subset (sample) of population.
Since, data set represents the heights of all students in the middle school with 600 students which is population here.
So, we do calculations to find population standard deviation.
Answer:
A. x + y = 5
Step-by-step explanation:
The slope of the equation is equal for parallel lines,
; Slope = (-1)
;Use the formula
(y - y(coordinate of the given point)) = slope × [(x - x(coordinate of the given point)]
; y - 1 = (-1)(x - 4)
; y - 1 = -x + 4...then move the variable (x) to the left hand side and then move (-1) to the right hand side
; x + y = 4 + 1
; Hence,
; x + y = 5
False because we dont know that because you didnt give us the problem'
